Aluminum windows

Aluminum windows are designed for demanding projects, where the main role is played by design, strength and the possibility of large glazed areas. They feature slim profiles, high static resistance and a minimalist look that underlines modern architecture. At SULKO we design aluminum windows as part of the overall construction concept. With superior systems, precision manufacturing and attention to detail, we are able to offer solutions that combine presentable appearance, comfort of use and long-term reliability — without compromise.

List of showrooms

Aluminum windows represent a technologically advanced solution for modern buildings, where the key combination of design, structural strength and long service life is key. Thanks to the high static resistance of aluminum, they make it possible to create large glazed areas with very slender frames, which bring more natural light into the interior and support the modern architectural appearance of the house.

Therefore, aluminum windows are often used in modern single-family homes, luxury residences, office buildings or architecturally demanding projects.

At SULKO we produce aluminum windows based on systems ALUPROF, which are among the most widely used aluminum window systems in Europe. These systems combine the high strength of aluminum profiles with advanced insulation technologies, which ensure very good thermal insulation properties and a long service life of the structure.

Window systems ALUPROF

For the production of aluminum windows we use modern systems ALUPROF MB-79N, MB-86N and MB-104 Passivethat allow you to adapt the solution to the specific requirements of the construction.

ALUPROF MB-79N

system MB-79N represents a modern aluminum profile with high thermal insulation and structural stability.

Main Features:

thermal insulation of the entire window Uw from 0.64 W/m²K
design depth of the frame approximately 70mm
the possibility of using double and triple glazing
three-chamber profile construction
high tightness against penetration of air and water

The MB-79N system is suitable for both new buildings and renovations of family houses.

ALUPROF MB-86N

For more demanding projects, we use the system ALUPROF MB-86N, which offers even higher thermal insulation and stability of the structure.

System parameters:

Thermal insulation of windows Uw from 0.62 W/m²K
construction depth of profiles up to 86 mm
security classes RC1 to RC4
very high water resistance and wind resistance
possibility of glazing up to 60—70 mm

This system is suitable for modern single-family homes, large glass walls or architecturally challenging projects.

ALUPROF MB-104 Passive

We offer a system for the most energy-efficient buildings MB-104 Passivethat meets the requirements of passive houses.

Main Features:

Thermal insulation of windows Uw around 0.7 W/m²K
construction depth of the sash 104mm
possibility of glazing up to 81mm
certifications Passive House Institute Darmstadt

This system is ideal for passive and low-energy homes.

Large glazed areas and modern architecture

One of the biggest advantages of aluminum windows is their ability to create large glazed structures.

Due to the high strength of aluminum, it is possible to produce:

large format windows
Glazed walls
balcony door
high wing weight design

For example, the MB-86N system allows structures with very high static resistance and large window sash sizes.

At the same time, slender frames mean more light in the interior and an elegant minimalist look of the facade.

Thermal insulation and energy efficiency

Modern aluminum windows today offer significantly better thermal insulation properties than older generations of aluminum systems.

Thanks to the use of:

Interrupted thermal bridge
multi-chamber profiles
Insulation inserts
high quality triple glazing

aluminium windows can achieve very good thermal insulation values and contribute to a reduction in heating costs.

Custom-made aluminum windows

At SULKO, we always design aluminum windows individually according to the specific construction.

When designing solutions, we take into account:

architecture of the house
size of glazed areas
energy efficiency requirements
design and color

Aluminium profiles can be painted in a wide range of RAL shades, textured surfaces and metallic colours, making them easy to adapt to the style of modern architecture.
